c The Schedule referred to in these Letters Patent and making part or the same To all chonifit 'may concern: l

Be itkuown'that weJonN FULLER and HERBERT FULLER, of Lockington, in the county of Shelby, and

'State of Ghio, have invented a new and useful Improvement in Combination Water-Wheel', and we do hereby declare that the following. is a full, clear, and exact description thereof, which will enable others skilled in the art to makeand use. the same, reference being had to theaccompanyin'g drawings, forming part of this specicatiomin whichv Figure 1 is a front view' of our improved wheel, partly in section, to yshow the construction.`

Figure 2 is a horizontal section of the same, taken through the line :z: e;fig. 1. i

4iSimilar letters of reference indicate correspondipg parts. v

Our invention has for itsobject'to furnish an iinproved `combination water-wheel,. which shall be so constructed andl arranged as'to utilize the power that has heretofore been lost by the friction of the water upon the scroll or guide-chutel, and at' the same time enabling small wheels to be used, s'o as to obtain the desired rapidity of motion Vwithout extra gearing; and

It consists in the construction and combination of the various 'parts ,ofthe wheel, as hereinafter more fully described.

A are the shafts, which are supported by and rei volve in bearings in the frame-work B, and thelower .i ends of which revol-vein steps, C, in the ordinary inanmer. Y

, Two or more shafts A are used, according to the le sited num'hervof wheels, and they are each provided l with a coupling, D, so that motion may be taken from either or' all of them, as may be desired.

lo the shafts A are attached cast-iron hubs, E, to

' which the buckets 11 are attached by screws, as shown in igs. 1 and 2f;

The buckets Fare made of heavy boiler-iron, and

are curved as shown inV fig. 2,' and-to their lower ends are attached, or upon theln are formed curved chutes, gG, extending rearward and downward, so that the water is discharged from each bucket below or nearly below the lower end of the next following bucket.

'lhe lower outer edges of the buckets F and ofl the buckets or chutes Gr are supported and held in their proper relative positions by a rim, H.

'They buckets are placedl-npon-the adjacent shaftsi a reversed position, .as shownin fig. 2, andthe wheels to the chute I is curved inward, so

are so arranged that the edges of the buckets may coincide with each other as the wheels revolve.

I is the chute, through which the water isintroduced into the wheels, and which is placed directly opposite the division-line between cach two wheels, as shown in gs. 1 and 2, so that the water may strike equally'and directly upon the buckets of both wheels without losing its power by friction upon scrolls or guide-chutes.

J is the casing, which entirely surrounds the'wheels," Aexcept the space or spaces occupied by the` chute or chutes I.

The casing J upon the side of the wheels opposite space between the wheels at an acute angle, as shown in iig. 2,*at'the point where the buckets F of the two wheels begin to separate, to prevent the water from escaping at the side edges of said buckets.

When more than two wheels of buckets are used the second chute I is placed upon th-e opposite side of the series 0f wheels from the first chute I, so that the wheel between the chutes will receive water from both chutes 'at the saine time, but upon opposite sides and in opposite directions.

K are gear-wheels, of the same size and the same number of teeth, one of which is attached to the upper part of each shaft A, so that the wheels of buckets may all move together, and with exactly the same y velocity.

L is the. gate, which moves up-v and down vertically through the chute I, to regulate or interrupt the inl ow ofthe water, as may be required.l

This construction allows 'small wheels to be used, so as to obtain the desired rapidity of motion without the employment of extra gearing, and the consequent loss of power from the friction of said gearing.

Having thus described our invention,

We claim as new, and desire t0 secure by .Letters Patentv A pairv of water-wheels, formed of hubs, E, curved buckets, F, and curved chutes, Gr, extending rearward and downward in the manuel' described.

JOHN FUILERL HERBERT FULLER.
